Description

Technical Field

[0001] The utility model relates to the technical field of charging adapters, and more specifically to a charging adapter with a charging protection structure. Background Art

[0002] The charging adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It is generally composed of components such as a casing, a transformer, an inductor, a capacitor, a control IC, and a PCB board. Its working principle is to convert AC input into DC output. It can be divided into wall-plug type and desktop type according to the connection method. It generally has overvoltage protection, short circuit protection, over-temperature protection, and over-power protection to avoid damage to the equipment during use and the risk of electric shock caused by working under problematic conditions.

[0003] In the prior art, the use of a charging adapter requires one to hold the charging plug with one hand and connect it to the charging socket. During this process, the power terminal needs to be focused and inserted into the socket. In order to facilitate holding, the outer surface of the plug is generally smooth. When plugging in, the plug needs to be pressed down hard, and the hand may slip when the plug and the socket are powered on, causing the finger to touch the live power terminal, resulting in the risk of electric shock. In view of this, we propose a charging adapter with a charging protection structure. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art, meet practical needs, and provide a charging adapter with a charging protection structure to solve the technical problem that the hand may slip during the insertion of the current charging adapter and cause the finger to contact the energized power contact piece.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a charging adapter with a charging protection structure, comprising an adapter shell, a charging cable is connected to the rear surface of the adapter shell, a power connection plate is arranged on the lower surface of the adapter shell, a magnetic partition opposite to the power connection plate is arranged on one side of the power connection plate, a connecting shaft is movably connected to one end of the partition, a card slot is symmetrically opened on the lower surface of the adapter shell, and a supporting edge is arranged on the outer surface of the partition.

[0006] The utility model is designed with a partition with magnetism on one side which fits with one side of the power connection plate. When the adapter shell is pressed to control the power connection plate to connect with the plug board, the palm slides downward to contact the partition, avoiding direct contact between the fingers and the power connection plate after sliding. At the same time, after use, the power connection plate can be pulled up and the edge of the partition can be pressed at the same time. With the support of the supporting edge, the power connection plate can be easily pulled out from the plug board, thereby facilitating the safe use of the charging adapter.

[0007] Preferably, the inner wall of the adapter shell is provided with a heat dissipation port, and the heat dissipation port includes a top rod, the outer surface of the top rod is fixedly connected to a limiting plate, and a plurality of inclined shielding plates are vertically arranged above the top rod, and adjacent shielding plates are connected by connecting ropes of equal length, and the interior of the shielding plate is movably connected to a support shaft fixedly connected to the inner wall of the adapter shell through a spiral spring; in the process of connecting the adapter shell and the plug plate, the top rod will be pushed upward by the supporting edge, and then the plurality of shielding plates will be pushed to rotate around the supporting shaft to a horizontal state under the action of the top rod, thereby improving the heat dissipation effect of the adapter shell when used in a machine room.

[0008] Preferably, the slot and the partition match each other, and the thickness of one end of the partition is the same as the depth of the slot, so as to avoid limiting the connection between the adapter housing and the plug board after the partition is rotated to a horizontal position.

[0009] Preferably, the shielding plate is located inside the upper end of the outer wall of the adapter housing, and the upper surface of the push rod contacts one side of the shielding plate located at the bottom; so that after the partition is inserted into the slot, the push rod can be controlled to lift the shielding plate.

[0010] Preferably, the length of the lower end of the push rod in the slot is equal to the distance between the upper end of the push rod and the baffle in the horizontal state; during the horizontal process of the partition, the push rod is pushed upward to press the baffle to the horizontal state, thereby improving the heat dissipation effect of the adapter housing during use.

[0011] Preferably, one end of the partition and the supporting edge form a lever structure for lifting the adapter housing; pressing one end of the partition facilitates the separation of the adapter housing and the plug plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model is designed with a magnetic partition on one side to fit with one side of the power connection plate. When the adapter housing is pressed to control the power connection plate to connect with the plug board, the palm slides downward to contact the partition, avoiding direct contact between the fingers and the power connection plate after sliding. At the same time, after use, the power connection plate can be pulled up and the edge of the partition can be pressed at the same time. With the support of the supporting edge, the power connection plate can be easily pulled out from the plug board, which is convenient for safe use of the charging adapter.

[0014] 2. The utility model also designs a push rod and a shielding plate structure to achieve the effect of pushing the push rod upward through the supporting edge, and then pushing a plurality of shielding plates to rotate around the supporting axis to a horizontal state under the action of the push rod, so that the internal space of the adapter shell is connected with the outside world, further solving the problem of poor heat dissipation caused by environmental limitations when used in a computer room.

[0021] like Figures 1 to 4 As shown, the utility model relates to a charging adapter with a charging protection structure, comprising an adapter housing 1, a charging cable 2 is connected to the rear surface of the adapter housing 1, a power connection plate 3 is arranged on the lower surface of the adapter housing 1, a magnetic partition 301 is arranged on one side of the power connection plate 3 and opposite to the power connection plate 3, a connecting shaft 302 is movably connected to one end of the partition 301, a card slot 303 is symmetrically opened on the lower surface of the adapter housing 1, and a supporting edge 304 is arranged on the outer surface of the partition 301.

[0022] In the embodiment of the utility model, the card slot 303 and the partition 301 match each other, and the thickness of one end of the partition 301 is the same as the depth of the card slot 303 ; wherein the height of the partition 301 is lower than the power connection plate 3 .

[0023] In the embodiment of the present utility model, one end of the partition plate 301 and the supporting edge 304 form a lever structure for lifting the adapter housing 1 .

[0024] As another embodiment of the utility model, the inner wall of the adapter housing 1 is provided with a heat dissipation port 4, and the heat dissipation port 4 includes a top rod 401, and the outer surface of the top rod 401 is fixedly connected to a limiting plate 402, and a plurality of inclined shielding plates 403 are vertically arranged above the top rod 401, and adjacent shielding plates 403 are connected by connecting ropes of equal length. The interior of the shielding plate 403 is movably connected to a support shaft 404 fixedly connected to the inner wall of the adapter housing 1 through a volute spring 405, and the shielding plate 403 is located inside the upper end of the outer wall of the adapter housing 1, and the upper surface of the top rod 401 contacts one side of the shielding plate 403 located at the bottom, and the length of the lower end of the top rod 401 in the slot 303 is equal to the distance between the upper end of the top rod 401 and the shielding plate 403 in the horizontal state.

[0025] Working principle: This embodiment provides a charging adapter with a charging protection structure. When the adapter housing 1 is pressed to connect the adapter and the plug board, the partition 301 will rotate on the outer surface of the connecting shaft 302 during the contact with the upper surface of the plug board, so that the partition 301 is gradually separated from the power connection plate 3. When the adapter and the plug board are connected, the partition 301 rotates to the inside of the card slot 303 and presses the top rod 401 upward to push the baffle plate 403 to rotate horizontally on the outer surface of the support shaft 404, thereby improving the heat dissipation effect of the adapter housing 1 when used in the machine room.
